Taxinomie. [1] Like other elasmobranchs, the skeleton of Otodus was composed of cartilage and not bone, resulting in relatively few preserved skeletal structures appearing within the fossil record.

Otodus sokolovi[1] is an extinct species or chronospecies of large shark in the family Otodontidae which may represent a transitional chronospecies between Otodus auriculatus and Otodus angustidens. A, 242 (4–6): 99–126, 5 fig., 1 tabl., 15 pl. & ESPINOSA-ARRUBARRENA, L. & GONZÁLEZ-BARBA, G. (2013), Mesozoic Fishes 5 – Global Diversity and Evolution: 9–34, ZALMOUT, I.S. These transitional fossils suggest a worldwide evolutionary event, and support the theory that Otodus eventually evolved into Otodus aksuaticus and thus initiated the Carcharocles lineage. Like other known megatooth sharks, the fossils of O. angustidens indicate that it was considerably larger than the extant great white shark, Carcharodon carcharias. A, 212 (1–6): 1–30, 9 pl., 1 fig, 3 tabl.
Hence, fossils of O. angustidens are generally poorly preserved.

[2] Scientists suggest that this shark at least reached 9.1 metres (30 ft) in total length (TL),[2] with a maximum length of 12.2 metres (40 ft). O. angustidens was a widely distributed species with fossils found in:[5] A fossil bed in South Carolina suggests that O. angustidens utilized the area as a birthing ground and nursery for their pups, as 89%of the teeth found in the area belonged to juveniles, 3% belonged to infants, and 8% belonged to adults. par Phanérozoïque, Otodus sokolovi , Priabonien , Dakhla (Maroc). To date, the best preserved specimen of this species have been excavated from New Zealand, which comprises 165 associated teeth and about 35 associated vertebral centra.

In the US and Britain the most widespread genus name for otodontids with serrated teeth is Carcharocles, and the owners of unserrated ones Otodus. As is the case with most extinct sharks, this species is also known from fossil teeth and some fossilized vertebral centra. This is really a brilliant tooth with super sharp serrations without damage. Informatsionnye materialy IGG AN SSSR. [3] This specimen is around 26 million years old. sokolowi, Procarcharodon cf.

They differ from the former with a less curved root and finer serrations and from the latter with more prominent and recurved cusps. [2] This shark is related to another extinct megatoothed shark, Otodus megalodon.[2]. Within the Carcharocles lineage, C. angustidens is the species succeeding C. sokolovi and is followed by C. [2] They differ from the former with a less curved root and finer serrations and from the latter with more prominent and recurved cusps. In countries of the former USSR, like Ukraine or Russia , all of these genera were attributed to Otodus , because scientists like Zhelezko and Kozlov [2] thought that the absence or presence of tooth serrations is not enough to place these sharks in different taxa . The name Otodus comes from Ancient Greek ὠτ (ōt, meaning "ear") and ὀδούς (odoús, meaning "tooth") – thus, "ear-shaped tooth".
